A wearable socio-biosensor device can include a plurality of sensors to detect bio-behavioral data of a subject, social data related to a proximity of the subject to other persons wearing socio-biosensor devices and bio-behavioral data measured during the time the subject is in close proximity to other persons, and environmental data related to the subject's environment. The socio-biosensor device can also include a body portion that includes: a non-transitory memory to store the bio-behavioral data, the social data, and the environmental data; a wireless transceiver to communicate with another device based on at least one of the bio-behavioral data, the social data, and the environmental data; and a rechargeable battery. The socio-biosensor device can also include an attachment mechanism that facilitates attachment of the body portion to the subject (e.g., attached to the subject's wrist). At least one of the plurality of sensors can be embodied in the attachment mechanism.
